BOAT-DETA CHING MECHANISM.

SPECIFICATION forming part of Letters Patent N70. 373,325, dated November 15, 1887.

Application filed April 6, 1887. Serial No. 233,906. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN W. WILLING, of Nantiooke, in the county of Wicomico and State of Maryland, have invented certain Improvements in Boat-Detachers, of which the following is a specification.

Figure I is a frontview of the detacher closed, and Fig. II is a side view of the same. Fig. III is a View of the detacher open.

Similar letters of reference indicate similar parts in all the figures.

A and B are crossed levers united to a strap, 0, by. means of a pivotal bolt, a. This strap is adapted for attachment in any suitable mannor to a block suspended from the boat'davit, which is not shown. The upper arms of the levers A and B are provided with weights 1) and c, which serve to open or separate the lower arms, ean'd f, asshown in Fig. III. The said lower arms are adapted for connection by means of a bolt, D, pivoted to the arm fand fitted to pass through a hole, 9, iuthe other arm, e, as shown in Fig. I. One of the lower arms, preferably the one 6, is furnished with a projection, 72, having a ring, is, at its end, to which the detaching-line Z is secured. The eyebolt E is fastened to the boat, which is not shown, and rests on the bolt D.

The boat is detached automatically as it strikes the water in view of the balls b and 0 opening or separating the arms 6 and f, or by hand by pulling the arm 6 from or over the end of the bolt D by means of the line Z.

It is obvious that the same effect is produced by pulling the arm f, with its bolt D, from connection with the arm 6.

When it is desired to lock the detacher, a pin, m, is passed through the bolt D and the projection h of the arm 0, as shown in dotted lines in Fig. I. This pin is connected to the ring k by means of a small line to prevent its being lost when not in use.

I claim as my invention- 1. In a boat-detacher, two weighted crossed levers pivoted to a suspensory strap and connected at their ends by means of a bolt which is pivoted to one of the said levers and fitted to pass through the other, substantially as and for the purpose specified.

2. In a boat-detacher, a pair of crossed levers pivoted to a suspensory strap connected at their lower ends by means of a bolt pivoted toone of the said levers and adapted to pass through the other, one of the said levers being provided with a ring or eye, to which a detaching-line may be secured, substantially as and for the purpose specified.

JOHN W. WILLING.
